Petunia plant named ‘Petlavgr’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Petlavgr’ characterized by its trailing, outwardly spreading and mounded plant habit, freely branching habit, freely flowering habit, single flowers that are lavender/rose in color, and good garden performance.

Latin name of the genus and species of the plant claimed: Petuniahybrida.

Varietal denomination: ‘Petlavgr’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Petuniaplant botanically known as Petunia hybrida and referred to by thecultivar name ‘Petlavgr’.

The new Petunia is the product of a planned breeding program conductedby the inventor in Enkhuizen, Netherlands. The new Petunia cultivar isfreely flowering with trailing and spreading plant habit and attractiveleaf and flower coloration.

The new Petunia originated from a cross-pollination made by the inventorin August 1999 of a proprietary selection of Petunia hybrida identifiedas code number ‘W973,’ not patented, as the female, or seed parent, witha proprietary selection of Petunia hybrida identified as code number‘R284,’ not patented, as the male, or pollen parent. The new Petunia wasselected as a single plant from the resulting progeny of thecross-pollination in a controlled environment in Enkhuizen, Netherlandsin June 2000.

Asexual reproduction of the new cultivar by terminal vegetative cuttingssince June 2000, in Enkhuizen, Netherlands has shown that the uniquefeatures of this new Petunia are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Petlavgr’ have not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, light intensity anddaylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Petlavgr.’ These characteristics incombination distinguish ‘Petlavgr’ as a new and distinct cultivar:

-   -   1. Trailing, outwardly spreading and mounded plant habit    -   2. Freely branching habit    -   3. Freely flowering habit    -   4. Single flowers that are lavender/rose in color    -   5. Good garden performance

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plantsof the new Petunia differed from plants of the female parent selectionin the following characteristic:

-   -   1. Plants of the new Petunia have lavender/rose flowers whereas        the flowers of the female selection are purple.

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plantsof the new Petunia differed from plants of the male parent selection inthe following characteristic:

-   -   1. Plants of the new Petunia have lavender/rose flowers whereas        the flowers of the male parent selection are light salmon.

Plants of the new Petunia ‘Petlavgr’ differ from the Petunia cultivarSurfinia Lilac (‘Sunlila’), not patented, in flower shape. The flowerpetals of the new Petunia have a rounded apex whereas the flower petalsof the Petunia cultivar Surfinia Lilac have a more pointed apex. Theplants from the new Petunia differ from plants of the Petunia cultivarSurfinia Lilac in flower throat color. The new Petunia has a lightthroat with brown and purple veins (176A and N74A) whereas the flowerthroat of Surfinia Lilac has no veins.

DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearanceof the new cultivar, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Petunia.

DESCRIPTION OF THE NEW CULTIVAR

The observations and measurements describe plants grown in Enkhuizen,The Netherlands., practice circumstances outdoor in windowboxes duringthe summer with day temperatures ranging from 18 to 25° C. and nighttemperatures ranging from 10 to 14° C. Plants used for the photographsand description were about 12 weeks from planting rooted cuttings.
